- Dr. Konstantin Raudive: Juergenson’s work came to the attention of a Latvian psychologist named Dr. Konstantin Raudive in the 1960s. At first skeptical, Raudive began his own experiments in 1967. He too recorded the voice of his deceased mother saying, “Kostulit, this is your mother.” (Kostulit was the boyhood name she always called him.) He recorded thousands of EVP voices.
